SP1 RC Hyper-V - VM properties hang

Frage

In the Hyper-V manager, when I either go to the VM properties or try and create a new VM, I have an hourglass over the properties window, and even after like 5 minutes, each component still shows "Loading..." and on the right pane there is text "Loading
setting data..."

After a while when I click on different properties, the second I click on them, the "Loading..." goes away and the property views normally on the right side. All of the properties show except for Add Hardware, Memory, and Processor. These three
components still show "Loading setting data..."

When I had the beta SP installed, everything was stable and worked fine. Not sure if this has been reported yet or if there is a fix for this. This has happened on two different servers that have had the beta installed, uninstalled, and
the RC patch installed.

I followed the steps of re-installing the new patch, but I did not disable RemoteFX and Dynamic Memory before the uninstall. After the SP1 RC patch, the VMs start up fine and I can access them fine via Connect, but the properties of the VMs is experiencing
this problem.

When I try and create a VM, at the "Specify Name and Location" page, a popup that says "Loading Page..." but does not go past that point. I have to End Task the window to get rid of the New Virtual Machine Wizard window.

I am wondering if I just need to use SCVMM, move the VMs onto a new server, then re-install Windows. These VMs are not in Prod, so I am not too worried about them.

I have now run this in PowerShell which has now enabled me to access the settings on the VMs again and create new VMs:

Import-Module ServerManager
Remove-WindowsFeature RDS-Virtualization

However the Add/Remove Role Services options are still greyed out for the Hyper-V role still.

On another PC which should meet the requirements for RemoteFX I am able to get to the properties of each VM and add a synthetic video adaptor but then I can't start the VMs due to this very unhelpful error:

Just wanted to let you all know that I was able to resolve this issue by removing the RDS Virtualisation Host (RemoteFX) role.

I was trying to use it on a non-SLAT enabled CPU.

Thanks

I had a similar experience to those in this thread when attempting to enable RFX this morning. It would seem that my CPU does not support SLAT/EPT as well. Unfortunately I cannot find any chart for Intel that includes a listing for EPT, but the following
thread suggests only VT-x version 2 supports it. This would only be available in their newer products.

Hyper-V Manager stops responding when I attempt to create a new virtual machine or edit an existing virtual machine’s
settings

If the Hyper-V Manager console, svchost.exe process, or RDVGSM service consistently stops responding when you attempt to create
a new virtual machine or edit an existing virtual machine’s settings, verify that the following Group Policy settings are not configured on the RemoteFX server:
